[Semiological profile of avascular necrosis of the femoral head in patients with AA and AS hemoglobins].

AIM: To search a possible difference in the avascular necrosis of the femoral head expression in patients with AA and AS hemoglobins seen at the Lomé Teaching Hospital Rheumatology Cinic (Togo).

METHODS

Medical records of patients seen at the Lomé Teaching Hospital, Rheumatology Clinic (Togo) during 17 years were studied. Have been included in the present study the patients affected by the avascular necrosis of the femoral head and having been the object of hemoglobi electroophoresis (79 patients: AS hemoglobin (29 patients) ; AA hemoglobin (50 patients). The comparison of the parameters rested on the analysis of variance.

RESULTS

Epidemiological and semiological comparison of the avascular necrosis of the femoral bead between the patients with AS hemoglobin and those having a normal hemoglobin didn't show a statistically significant difference.

CONCLUSION

The presence of AS hemoglobin in avascular necrosis of the femoral head patients must not influence the gait aiming the search of an etiology or risk factor.
